Transactional lock-free execution of lock-based programs

This paper is motivated by the difficulty in writing correct high-performance programs. Writing shared-memory multi-threaded programs imposes a complex trade-off between programming ease and performance, largely due to subtleties in coordinating access to shared data. To ensure correctness programmers often rely on conservative locking at the expense of performance. The resulting serialization of threads is a performance bottleneck. Locks also...
